如何识别SQL服务器的端口号

Question

I Install SQL server in my system and I have to check on which port number SQL is working in my system

Answer 1

1. Open SQL Server Management Studio
2. Connect to the database engine for which you need the port number

3. Run the below query against the database

   select distinct local_net_address, local_tcp_port from sys.dm_exec_connections where local_net_address is not null

The above query shows the local IP as well as the listening Port number

Answer 2

1. Open Run in your system.

2. Type %windir%\\System32\\cliconfg.exe

3. Click on ok button then check that the "TCP/IP Network Protocol Default Value Setup" pop-up is open.

4. Highlight TCP/IP under the Enabled protocols window.

5. Click the Properties button.

6. Enter the new port number, then click OK.

This query works for me:

SELECT DISTINCT 
    local_tcp_port 
FROM sys.dm_exec_connections 
WHERE local_tcp_port IS NOT NULL

要检查在所有端口上侦听的所有应用程序，请使用以下命令：

netstat -ntpl

Answer 7

PowerShell solution that shows all of the instances on the host as well as their incoming traffic addresses. The second bit might be helpful if all you know is the DNS:

ForEach ($SQL_Proc in Get-Process | Select-Object -Property ProcessName, Id | Where-Object {$_.ProcessName -like "*SQL*"})
{
    Get-NetTCPConnection | `
     Where-Object {$_.OwningProcess -eq $SQL_Proc.id} | `
      Select-Object -Property `
                                @{Label ="Process_Name";e={$SQL_Proc.ProcessName}}, `
                                @{Label ="Local_Address";e={$_.LocalAddress + ":" + $_.LocalPort }},  `
                                @{Label ="Remote_Address";e={$_.RemoteAddress + ":" + $_.RemotePort}}, State | `
      Format-Table
}
